How to Reduce Advanced Glycation End Products

Reducing advanced glycation end products (AGEs) in your diet can reduce the risk of chronic diseases and prevent premature aging!

What are AGEs?

You may have heard of AGEs before, but what exactly are they? AGEs, or advanced glycation end products, are a type of harmful compound that forms when proteins or fats combine with sugars in the bloodstream through a process called glycation. These compounds are known to increase inflammation and oxidative stress and can damage tissues, contributing to the development of various chronic diseases. 

Where are AGEs found?

AGEs, also known as glycotoxins, are form when high fat animal foods, such as meat is exposed to high heat. Cooking methods like grilling, frying, and roasting, as well as processed foods tend to be high in AGEs.

Although the body has a way of eliminating AGEs, excessive AGEs in our circulation can produce harmful effects. Exposure to AGEs has been linked to an increased risk of inflammation, oxidative stress, and cell damage. These effects can lead to the development of chronic diseases such as diabetes, cardiovascular disease, and Alzheimer’s disease.

How can you avoid AGEs?

The main source of AGEs is from our diet. While the formation of AGEs is part of normal metabolism, excessive amounts may be harmful. There are several ways you can reduce exposure to AGEs.

  1. Cook using moist methods, such as steaming, poaching or boiling, that don’t involve high dry heat
  2. Limit your consumption of processed foods
  3. Use shorter cooking times
  4. Cook food gently using lower temperatures
  5. Include acidic ingredients, such as lemon juice and vinegar which inhibit the formation of AGE

The standard American diet is often high in processed foods that have higher levels of AGEs, so it’s important to limit your intake of these foods. Some processed foods that are high in AGEs include:

  • Hot dogs
  • Bacon
  • Sausages
  • Chips
  • Pizza

Carbohydrate-rich foods such as vegetables, fruits, whole grains, and milk tend to be lower in AGEs, even after cooking.  Foods that are lower in AGEs include:

  • whole-grain bread and pasta
  • yogurt
  • beans and legumes
  • fruit
  • low-fat milk products

There is evidence that maintaining a healthy gut microbiome may also contribute to lower levels of circulating AGEs. This is because gut bacteria have the ability to degrade AGEs during the digestive process. Consuming a diet rich in probiotic foods such as fermented foods -kimchi, sauerkraut, yogurt, kefir – and taking a probiotic supplement can support a healthy gut microbiome. You can learn much more about gut-friendly foods in a previous post – How to Heal Your Leak Gut.

Lastly, consuming a diet rich in antioxidants and phytochemicals may also contribute to reducing cell damage caused by AGEs.

A Diet low in AGEs

Human studies suggest that a low-AGE diet reduces oxidative stress and inflammation. These studies revealed increased insulin sensitivity, which can help maintain weight loss over time, as well as reduced markers of inflammation.

So what does a low-AGE diet look like? Here are two sample menus with some of my favorite meal plan recipes that utilize ways to reduce AGE levels:

Menu 1

Breakfast: Orange Cardamom Overnight Oats

Lunch: Kale and Sweet Potato Salad with Walnuts

Snack: Yogurt with Blueberries

Dinner: Whole-grain Pasta with Beans, Garlic, and Arugula served with Simple Poached Salmon

Menu 2

Breakfast: Chocolate Fudge Smoothie with Hemp Seeds

Lunch: Quinoa Tabbouleh

Snack: Low-fat Cottage Cheese with Raspberries

Dinner: African Peanut Stew with Sweet Potatoes and Spinach

Final Thought

The current AGE research demonstrates that a significantly reduced intake of AGEs can be achieved by increasing the consumption of fish, legumes, low-fat milk products, vegetables, fruits, and whole grains and by reducing intake of solid fats, fatty meats, full-fat dairy products, and highly processed foods.

Reducing your exposure to AGEs is a good way to support your overall health, prevent premature aging and reduce your risk of chronic disease. Making simple changes to the way you cook and eat can help protect your health in the long term by reducing the risk of cardiovascular disease, cancer, diabetes, and Alzheimer’s disease.

How to Heal Your Leaky Gut

Harvard Health calls it a “medical mystery” and “mysterious ailment.” It’s been linked to everything from gut troubles, autoimmune diseases, and even mental health concerns.

I’m talking about “leaky gut” or “intestinal permeability”—have you heard of it?

Many doctors and the established medical community may not recognize it, but there is growing research to suggest it is associated with many health conditions. Working in tandem with integrative medicine doctors, I have been able to help many people return to better health by healing their leaky gut.

What exactly is “leaky gut?” Do you have it? How does it happen? What can you do about it?

What is “leaky gut?”

Your gut (gastrointestinal system) is not just a 30-foot-long muscular tube (tract) that starts at your mouth and ends with you going to the bathroom. In fact, It’s a vast and complex system with many functions. It breaks down food into smaller digestible bits, keeps it moving through the gastrointestinal tract, and skillfully absorbs water and nutrients while keeping out harmful substances. More and more research shows that these essential gut functions are interconnected throughout your body—to everything from your heart to your brain.

Your gastrointestinal tract is lined with millions of cells, all side-by-side in a single layer. In fact, this layer, if spread out flat, covers 400m2 of surface area! Those intestinal cells help the body to absorb what we need from foods and drinks, while keeping out what needs to stay out. It acts as a gatekeeper allowing in what your body uses, and keeping out the rest which ends up as waste. This ability to selectively allow some things in our gut to be absorbed while keeping others out is only possible if the cells are working properly and physically joined together very tightly. The bonds that keep the cells tightly together are called “tight junctions.”

Leaky gut happens when the tight junctions aren’t so tight anymore. The cellular barrier is irritated and weakened, allowing tiny holes to appear. These perforations allow things that normally would stay out of the bloodstream get into the bloodstream. Things like food particles, waste products, and bacteria.

When these get into the bloodstream your immune system is triggered to start fighting them. Similarly to how your immune system starts fighting the cold virus and causes inflammation. This immune reaction is normal and helps keep you healthy. 

Do you have a leaky gut?

The symptoms of leaky gut are similar to those of other digestive conditions like inflammatory bowel disease, celiac disease, and Crohn’s disease. Symptoms can include diarrhea, constipation, cramps, bloating, food sensitivities, or nutrient deficiencies. 

But, because the food particles, toxins, and bacteria have been absorbed into the bloodstream which travels throughout your body, symptoms can appear anywhere. Studies show that leaky gut may feel like fatigue, headaches, confusion, difficulty concentrating, joint pain, or skin problems (e.g., acne, rashes, eczema). Leaky gut is also linked with diabetes, polycystic ovarian syndrome, liver disease, chronic fatigue syndrome, and autoimmune diseases such as lupus and multiple sclerosis. There may even be links to anxiety and depression.

Many of these gut and non-gut symptoms and conditions are linked to chronic inflammation, but more research is needed to understand how they are connected.

Even if you have some of these symptoms, the fact is, it’s very difficult to diagnose a leaky gut, nor how leaky it is. This means that, while there are some biomarker tests, there isn’t a reliable diagnostic test available just yet. So, it’s difficult to say whether your symptoms are from leaky gut, or whether leaky gut is a symptom of another issue. 

What causes leaky guts?

It’s not 100 percent clear what causes those bonds to loosen and result in tiny perforations in the gut barrier. In fact, we’re just starting to understand how the gut barrier functions and there is a lot of ongoing research.

Part of leaky gut may be due to the genes you inherit from your parents. It can also be from medications or gut infections. Leaky gut is also linked to eating a diet that is low in gut-friendly fiber (adults should aim for 25-30 g of fiber per day). It can also be from consuming too much added sugar and saturated fat. Leaky gut may even result from stress or an imbalance in the diversity and numbers of your friendly gut microbes.

Also, as you age your cells can get damaged more easily and heal slowly, including the cells that line your gut. This can leave you more susceptible to loosening of the gut barrier.

What can you do about a leaky gut?

One way to approach a suspected leaky gut is to address inflammation and eat a more gut-friendly diet. This means reducing excessive alcohol and processed foods that tend to be high in fat and sugar or artificial sweeteners. It’s also a good idea to avoid foods that you’re allergic or sensitive to. For example, if you have diagnosed celiac disease, you want to be sure to stay away from gluten, as exposing your gut to it can cause a large inflammatory response.

Instead, enjoy more foods rich in gut-friendly probiotics and fiber – which is a prebiotic that feeds your friendly gut microbes. These include:

  • yogurt or kefir
  • fermented foods (e.g., kimchi, sauerkraut, and miso)
  • fruits and vegetables (e.g., berries, oranges, broccoli, carrots, and zucchini)
  • nuts and seeds (e.g., walnuts, cashews, and chia seeds)
  • Whole grains (e.g., oats, corn, and quinoa)

If you’re going to proactively increase your fiber intake, do it over several days or weeks because sudden increases in fiber can cause gas, bloating, and other gut discomfort. If you have IBS, check with a Registered Dietitian to see if certain fibers may worsen your condition and which are recommended.

Also, regular exercise can help your digestive system. This means taking even a 15- or 20-minute walk after you eat to help you digest your food. And don’t forget the importance of stress management, quality sleep, and not smoking.

If you plan on making changes to your diet and lifestyle, consider keeping a journal to help see if the changes are helping your symptoms.

Take Action

When it comes to leaky gut, a few simple shifts toward a gut-friendly diet can help you navigate your symptoms and start the healing process.

A leaky gut is associated with gut and non-gut symptoms. It’s an inflammatory condition that has been linked to metabolic disorders, autoimmune conditions, and even mental health. There is no good diagnostic test at this time to know for sure if you have it or not. And remember, this is still a rather new area of research, so more information emerges all the time. 

In the meantime, if you have symptoms that suggest a leaky gut, you can move toward a more gut-friendly diet. Try cutting down on alcohol, processed foods, and any that you may be allergic or sensitive to. Replace these foods and drinks with ones higher in gut-friendy probiotics and fiber. And remember that regular exercise, stress management, and quality sleep are great lifestyle strategies for your gut and the rest of your body.
